- Welding is a process that joins two or more pieces of metal by melting them together with the use of electricity. This causes the metal to fuse, making the two pieces into one. Welding is different from other metal joining techniques, such as brazing and soldering, which do not use electric an arc or melt the metals that are being attached together.
- Taimco provides you with a comprehensive selection of welding services and fabrication solutions. From Stud, Spot, Robotic, MIG and TIG, our cutting-edge facility has some of the industry’s most skilled craftsmen who are impeccable in their attention to your project’s details.
- MIG welding from Taimco is a high-speed manual process that’s fairly precise but delivers a high-strength weld, this technique is best for medium to large quantities of production. MIG welding is ideal for Aluminum, mild steel, and stainless steel.
- TIG welding from Taimco is a low-speed but incredibly precise welding process that delivers a very high-strength weld. This procedure of welding is best for low volumes or precision welds. TIG welding is ideal for stainless steel and aluminum fabrication.
- Spot welding is used in a variety of industries, including automotive, aerospace, rail, white goods, metal furniture, electronics, medical building and construction, Given the ease with which this method can be automated when combined with robots and manipulation systems, it is the most common joining process in high-volume manufacturing lines and has in particular been the main joining process in the construction of steel cars for over 100 years.

- the Joint Design – provides information on the type of joint, dimensions and tolerances. It specifies if there is need for backing, back gouging or any other type of joint preparation.
- Base Metal – material number, subgroup (if any), thickness range that can be welded and the diameter if using tubular components.
- Filler Metal – specification of the filler metal, F- and A- numbers. It can also provide nominal chemistry composition if it is not a classified filler metal.
- Position – specifies the position (flat, horizontal, vertical, overheat) including pipe rotation, if any. Also provides the progression (up or down) if the weld is in the vertical position.
- Preheat and Interpass Temperature – provides the minimum preheat and Interpass temperature. Some base materials will also require a maximum Interpass temperature
- Heat Treatment – this may include post weld heat treatment to prevent hydrogen induced cracking, to regain dimensional tolerance, to reduce or eliminate residual stresses and/or to achieve the desired mechanical properties. It will provide the heat treatment temperature and holding time.
- Shielding Gas – shielding gas to be used, shielding gas components if it is a mixed gas including the percentage of each gas. Shielding gas flow rate must also be specified.
- Electrical Characteristics – this section specifies the current type (AC or DC) and polarity (+ or – for DC). It will also specify the mode of metal transfer.
- Welding Variables (Procedure) – in this section the wire feed speed (and/or amperage), voltage, travel speed, contact tip to work distance, work and travel angles are specified.
Required Components of Welding Procedure Specifications:Regardless of what position you hold, if you work in the metal industry you have heard of welding procedures specifications, a welding procedure simply means the selection of a few variables such as amps and volts and other technical steps to get to the best workman ship and finished products.
