  1. Types of Welding

    Leave a Comment

    Welding is a joining process that produces coalescence, or merging together, of materials by heating, with or without the application of pressure, or by the application of pressure alone, and with or without the application of filler metal. The primary difference between welding and other joining techniques such as soldering is that the material of the parts is melted to facilitate a molecular bond between parts. This allows for a joint that is as strong or stronger than the component materials being joined. Welding is the most efficient method of permanently joining metal.

    Types of Welding

    Depending on the material and intended product application, there are a variety of different types of welding. Each method uses different tools, heat sources, materials, or equipment to produce the desired results. Below is a short summary of the most common welding methods. 

    MIG Welding

    Metal inert gas (MIG) welding, also known as gas metal arc welding, involves creating an electric arc between a consumable wire electrode and the workpiece. The wire is continuously fed into the arc, allowing it to melt and serve as the filler metal for joining the two workpieces together. Throughout the process, the weld pool is protected from contamination through the use of a shielding gas.

    Pulsed MIG Welding

    Pulsed MIG welding is a variant of conventional MIG welding that involves pulsating the electric current rather than having a steady amperage. This process ensures low levels of spattering and is compatible with a variable working range from light gauge to thick gauge sheets.

    Low Splatter Control (LSC) Welding

    LSC welding is a type of MIG welding that offers high-quality weld seams with high arc stability, minimal spattering, and an increased deposition rate. This process uses a penetration stabilizer, which enables constant penetration in the spray arc, even with possible stick out change.

    Pulse Multi Control (PMC) Welding

    PMC welding is another type of MIG welding that relies on a modified pulsed arc. This method utilizes arc length and penetration stabilizers to ensure faster welding speeds and higher quality weld seams.

    Cold Metal Transfer (CMT) Welding

    CMT welding offers very low heat input and an extremely stable arc, regardless of weld speed or the surface of the workpiece. This ensures optimum results when joining different materials such as aluminum and steel. This method also features reversing wire electrode movement, which reduces the amount of spattering.

    TIG Welding

    Tungsten inert gas (TIG) welding, also called gas tungsten arc welding (GTAW), creates a weld using a non-consumable electrode to generate an electric arc and a filler metal. An inert shielding gas is used to protect the electrode and weld area from contamination. Since the welding operator must carefully guide the electrode and filler metal, this process allows for more control and precision compared to other welding methods. 

    Stick Welding

    Stick welding is a simple method that uses a consumable electrode rod that melts and bonds with heated material to join two components. It creates bonds even with rust and unclean surfaces, making it ideal for outdoor construction. Since an inert gas envelope is not produced for stick welding, the welds may exhibit oxidation and porosity.

    Flux Core Arc Welding (FCAW)

    Flux core arc welding (FCAW) is very similar to MIG welding in that it uses a continuous filler wire electrode to create an arc. However, the electrode used in FCAW processes is a hollow tube filled with flux that outgasses when heated. Similar to the inert gases in MIG and TIG welding, this flux outgassing protects the weld from exposure to atmospheric oxygen, thereby creating strong, reliable weld joints.

  2. What Are AWS D1.1 and AWS D14.1?

    Leave a Comment

    The experts at Miracle Welding Inc. can meet nearly any welding needs, whether you require Arc welding, MIG welding, TIG welding, or other solutions. To help provide top-quality welding services, we work based on certain welding codes that facilitate uniformity and efficiency. There are many welding codes that have been developed over time, setting various requirements for testing, inspection, maintenance, and other aspects of welding.

    Two common welding codes that you may encounter are AWS D1.1 and AWS 14.1. The American Welding Society (AWS) developed these specifications to provide standards for steel structural welding and various types of construction and earth-moving equipment, respectively. Here we’ll go over what these specific welding codes cover and how they apply to different welding applications.

    AWS D1.1

    what is aws d1.1Welding code AWS D1.1 is the most commonly used welding code in the U.S. and is used as the primary quality standard for many projects involving steel welding. Fabricators often use this code to qualify welders and welding procedures, but it can also help reduce the costs of projects by facilitating consistent quality.

    There are several provisions that AWS D1.1 governs in different sections. These sections include:

    • General Requirements. In this section, basic information is contained regarding the limitations and general scope of the code.
    • Design of Welded Connections. This section details the requirements for different types of tubular and nontubular products.
    • Prequalification. This section covers the prequalification of Welding Procedure Specifications (WPSs), detailing the requirements for exempting them from qualification.
    • Qualification. After prequalification of WPSs, this section is used to determine the qualification requirements for both WPSs and welding professionals before performing welding procedures.
    • Fabrication. This section indicates specifications for assembly, preparation, and overall workmanship of structures made with welded steel.
    • Inspection. Inspectors use this section to learn the criteria for responsibilities and qualifications of inspectors, along with procedures for visual inspections and nondestructive testing (NDT) and acceptance criteria for production welds.
    • Stud Welding. Prior to performing stud welding procedures, this section details requirements for welding studs to steel structures.
    • Strengthening and Repair of Existing Structures. This section lays out the basic details regarding welded modification or maintenance of existing steel structures.
    • Tubular Structures. This section provides additional details about requirements for different tubular structures.

    These standards can help welders determine how to calculate the allowable strength required for specific welds. They also provide specific requirements that welders and inspectors need to meet to eliminate the need for testing for the qualification of welding procedures. In addition, AWS D1.1 indicates requirements for welding consumables, various base welding materials, and general workmanship for structures featuring steel construction.

    AWS D14.1

    AWS D14.1 is listed as the Specification for Welding of Industrial and Mill Cranes and Other Material Handling Equipment. This code is used to specify welding requirements for manufacturing cranes for different mill, powerhouse, industrial, and nuclear facilities. It also applies to certain types of material handling equipment and machinery that are used for transporting or supporting loads.

    The different provisions that AWS D14.1 specifies include the welding, producing, providing, recording, controlling, and inspecting standards for the welding of both overhead cranes and material handling equipment. In the process, this welding code helps maintain consistent quality and repairs for welding cranes and material handling systems. However, the specification doesn’t apply to crawler- or construction-type cranes, and separate standards apply to railing used in these applications under welding code AWS D15.2.

    Aluminum welding is a fabrication process that uses heat and pressure to join two components made from aluminum or aluminum-based alloys. Compared to welded assemblies made from other materials, such as steel, welded aluminum assemblies do not demonstrate the same level of strength as their parent materials. As such, it is imperative that industry professionals choose the right base material and welding technique to form the strongest bond possible between aluminum components.

    Selecting these elements, however, can be challenging as aluminum welding operations vary greatly in regard to the base materials and welding techniques employed depending on the product and production specifications. The following article provides an overview of aluminum welding so customers can better understand what aluminum materials and welding techniques are best suited for their project.
