WELDING TECHNOLOGY by Mind Map: WELDING TECHNOLOGY

1. 1

1.1. Introduction of Welding Technology

1.1.1. Definition: The melting of metal to create goods. A fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool.

1.1.2. Welding is usually used on metals and thermoplastics but can also be used on wood.

2. 2

2.1. Types of Welding Processes

2.1.1. Fusion-state Welding

2.1.1.1. Coalescence is accomplished by melting the two parts to be joined, in some cases adding filler metal to the joint

2.1.1.1.1. Arc Welding

2.1.1.1.2. Resistance Spot Welding

2.1.1.1.3. Oxyfuel Gas Welding

2.1.2. Solid-state Welding

2.1.2.1. Heat and/or pressure are used to achieve coalescence, but no melting of base metals occurs and no filler metal is added

2.1.2.1.1. Forge Welding

2.1.2.1.2. Diffusion Welding

2.1.2.1.3. Friction Welding

3. 3

3.1.2. Surfacing

3.1.3. Plug

3.1.4. Slot

3.1.5. Fillet

3.1.6. Groove

4. 4
