      About products and suppliers

      Wholesale internal welding products and related equipment is designed for special applications. Metal that can be welded together includes steel, stainless steel, galvanized steel, aluminum alloy, copper alloy, carbon steel, etc. A stationary spot welder can perform one weld at a time; different machinery must apply multiple spots for a weld. There are various types of welding machines that are available at Alibaba.com. Request a quote and ask a supplier what is available for spot welding and other types of welding in the industry. Shop online today at Alibaba.com for welding equipment at wholesale prices.



      Projection welding is a beneficial method for joining sheet metal Other welding projections are needed on nuts, bolts, sheet edge, cross wire, wire to sheet, T joint, or even overlap of material, etc. Depending on the type of work you are doing, there are certain things to consider. The primary voltage of 230v will allow you to run a portable internal welding; for a fixed welder and other types of equipment, you will need 400v and an attachment. The power influences the machine’s ability to weld thicker sheet metal. Also, browse our inventory for other related welding equipment, welders, accessories, and tools. Read the instructions carefully before using any of the heavy duty welding equipment to avoid injury.



      Allibaba.com has incredible wholesale solutions for internal welding ranging for different types of welding, spot welding, projection welding, and seam welding. If you're looking for welding equipment or a multi-spot resistance welding machine at a competitive price contact a manufacturer for specifications on all welding equipment.
