Key Welding Processes Covered

So, what specific welding processes can you learn about from this handbook? Here’s a sneak peek:

Arc Welding

Arc welding is one of the most common welding methods, and the IIW Handbook dedicates significant attention to it. Arc welding involves using an electric arc to create heat, melting the base metals and filler material to form a weld. The handbook covers several arc welding variations, including:

• Shielded Metal Arc Welding (SMAW): Also known as stick welding, SMAW is a manual process where a coated electrode is used to create the arc. The coating protects the weld from atmospheric contamination. The handbook details electrode selection, welding techniques, and troubleshooting for SMAW.
• Gas Metal Arc Welding (GMAW): GMAW, or MIG welding, uses a continuous wire electrode fed through a welding gun, with a shielding gas protecting the weld. The handbook explains different GMAW modes (e.g., spray transfer, pulsed transfer), gas selection, and optimizing parameters for various materials.
• Gas Tungsten Arc Welding (GTAW): GTAW, or TIG welding, uses a non-consumable tungsten electrode to create the arc. A shielding gas (usually argon) protects the weld. The handbook covers GTAW techniques for welding different metals, including aluminum, stainless steel, and titanium.
• Submerged Arc Welding (SAW): SAW is an automated process where the arc is submerged under a layer of flux. The flux protects the weld and adds alloying elements. The handbook discusses SAW setup, flux selection, and applications for high-volume welding.

Resistance Welding

Resistance welding relies on heat generated by the resistance to electric current flow through the materials being joined. The IIW Handbook provides extensive coverage of resistance welding processes, including:

• Spot Welding: Spot welding is commonly used to join sheet metal by applying pressure and electric current through electrodes. The handbook details electrode design, welding parameters, and quality control for spot welding.
• Seam Welding: Seam welding is similar to spot welding but produces a continuous weld seam. It’s often used for making leak-tight joints. The handbook explains seam welding techniques, wheel electrode selection, and applications.
• Projection Welding: Projection welding involves welding at specific points created by projections on one of the workpieces. The handbook covers projection design, electrode configuration, and welding parameters for different materials.

Other Welding Processes

Beyond arc and resistance welding, the IIW Handbook covers a range of specialized welding processes:

• Laser Beam Welding (LBW): LBW uses a focused laser beam to create a narrow, deep weld. The handbook discusses laser types, welding parameters, and applications for high-precision welding.
• Electron Beam Welding (EBW): EBW uses a beam of electrons in a vacuum to create a weld. The handbook covers EBW setup, vacuum requirements, and applications for welding dissimilar metals.
• Friction Welding: Friction welding uses friction to generate heat and create a weld. The handbook explains different friction welding methods (e.g., rotary friction welding, linear friction welding) and their applications.

What You’ll Find Inside the Handbook

Okay, so we know it's comprehensive, but what exactly will you find when you crack open the IIW Welding Processes Handbook PDF? Expect to see:
