The standard integrated spot welding package includes a vertically articulated, six-axis, ES-165 robot with a 165 kg payload. The P-point working envelope is 2650 mm (104 inches). The robot can reach below its own base, and can travel in an arc approximately 360 around the base. However, it is possible to restrict the base axis with hard stops. Spot Welding ParametersOne general criterion of resistance spot-welding is that the weld shall have a nugget diameter of 5*t 1/2, t being the thickness of the steel sheet. Thus, a spot weld made in two sheets, each 1 mm in thickness, would generate a nugget 5 mm in diameter according to the 5*t ½ -rule.

What is Spot Welding? (A Complete Welding Process Guide)

Due to its lower thermal conductivity and higher electrical resistance, steel is comparatively easy to spot weld, with low carbon steel being most suited to spot welding. However, high carbon content steels (Carbon equivalence > 0.4wt%) are prone to poor fracture toughness or cracking in the welds as they tend to form hard and brittle Which Metals Can Be Welded and Why?Aug 04, 2017 · Stick welding can be used to weld steel, iron, aluminum, copper, and nickel. Browse Welding supplies for your Project. Unlike stick welding, gas metal arc welding (or GMAW) does not have a coating over the electrode rod. Instead, the welding gun disperses a shielding gas that protects against contaminants.

Guidelines For Resistance Spot Welding

SPOT WELDING can cause fire or explosion. Sparks can fly off from the welding arc. The flying sparks, hot workpiece, and hot equipment can cause fires and burns. Accidental contact of elec-trode to metal objects can cause sparks, explosion, overheating, or fire. Check and be sure the area is safe before doing any welding.
