Arrow Tool & Stamping’s Welding Processes for your Metal Product:
Spot Welding of your Metal Product
A 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 pass current through the sheets. The advantages of this method include efficient energy use, limited work piece deformation, and no required filler materials. Weld strength is significantly lower than with other welding methods, making the process suitable for only certain applications on ferrous metals.
Gas Metal Arc Welding (GMAW) of Your Metal Product
Also known as metal inert gas or MIG 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. Since the electrode is continuous, welding speeds are greater for GMAW than for that of GTAW. GMAW is well suited to production welding. This process can be applied to a variety of ferrous metals.
Gas Tungsten Arc Welding (GTAW) of Your Metal Product
Tungsten inert gas or TIG welding, is a manual welding process that uses a tungsten electrode, an inert or semi-inert gas mixture, and a separate filler material. Especially useful for welding thin metals, this method is characterized by a stable arc and high quality welds, but it requires significant operator skill and can only be accomplished at relatively low speeds. TIG can be used on nearly all weldable metals, though it is most often applied to stainless steel, aluminum and light metals.
Brazing of Your Metal Product
A group of joining processes that produces coalescence of materials by heating them to the brazing temperature in the presence of a filler metal having a liquidus above 450 0 C (840 0 F) and below the solidus of the base metal. The filler metal is distributed between the closely fitted faying surfaces of the joint by capillary action.
Soldering of Your Metal Product
A joining process of metallic objects where coalescence or attachment is obtained by heating to a suitable low temperature, usually below 450 0C (840 0F), using non-ferrous filler alloys (solders) which melt at temperatures lower than that of the base materials to be joined. Capillary attraction helps in spreading the solder between the properly fitted surfaces.
