Welding Services

A-1 AccuTech's custom fabricating services provide a complete range of welding processes including TIG, MIG, Spot and CNC Plasma Welding. We have the experience and skill required to weld various types of metals, and we are highly proficient in welding stainless steel. When used in combination with our deep drawing and bending and forming capabilities, we are able to achieve a high degree of precision and design flexibility.

Welding is a fabrication process that joins materials (usually two or more pieces of metals) by causing the pieces to bond together. This is often done by melting the objects and adding a filler substance to form a pool of molten material (the weld pool) that cools and solidifies to become a strong joint, resulting in one continuous solid piece.

Our engineering team will review your design to determine the most effective process for your application and product.


TIG (tungsten inert gas) welding is a manual welding process that uses a non-consumable tungsten electrode, an inert or semi-inert gas mixture. Filler metal is added separately, making this process very flexible, though some welds do not require it. Especially useful for welding thin sections of stainless steel, this process produces welds of excellent quality and finish. It requires significant operator skill and can only be accomplished at relatively low speeds.

MIG (metal inert gas) welding is a semi-automatic or automatic process that uses a continuous wire feed as an electrode and an inert or semi-inert gas mixture to protect the weld from contamination. The process is used to weld most commercial metals including stainless steel, aluminum, steel and copper and can be used to weld in any position when appropriate welding parameters and equipment are selected.

Spot welding is a popular resistance welding method used to join overlapping metal sheets of up to 3 mm thick. Two electrodes are simultaneously used to clamp the metal sheets together and to pass a current through the sheets. The advantages of this method include limited work piece deformation, high production rates, efficient energy use, easy automation, and no required filler materials. Weld strength is significantly lower than with other welding methods, making the process suitable for only certain applications.

Plasma arc welding also uses a tungsten electrode but uses plasma gas to make the arc. The arc is more concentrated than other welding methods, making transverse control more critical and generally restricting the technique to a mechanized process. Plasma welding is also much faster than other methods and can be used for deeper and narrower welds. Because of its stable current, the method can be used on a wider range of material thicknesses.
