300-series stainless steel Tyler double-welding-wheel resistance seam welding process

Abstract

The invention discloses a 300-series stainless steel Tyler double-welding-wheel resistance seam welding process which is characterized by adopting welding process parameters controlled during Tyler double-welding-wheel resistance seam welding comprising welding current, welding speed, overlap amount, No.1 welding wheel pressure, and No.2 welding wheel pressure, wherein the welding speed is 750cm / min, the overlap amount is 2mm, the No.1 welding wheel pressure is 950kg, the No.2 welding wheel pressure is 950kg, and a value of the welding current is adjusted according to the thickness of 300 stainless steel strip steel. The 300-series stainless steel Tyler double-welding-wheel resistance seam welding process provided by the invention has the beneficial effects that the 300-series stainless steel Tyler double-welding-wheel resistance seam welding process parameters with the thickness being smaller than or equal to 1.5mm are provided, and the welding current and the welding seam overlap amount are set according to the strip steel thickness, so that the welding seam fusion performance is improved, the welding seam strength and toughness can be optimized, a welding seam is flat and smooth, the occurrence of the phenomena such as cracking, incomplete fusion, lack of penetration and weld penetration is avoided, the production processing demand of an annealing-pickling production line ismet, the product quality is ensured, and the yield is improved.

Description

technical field [0001] The invention belongs to the technical field of stainless steel welding, and in particular relates to a Taylor double welding wheel resistance seam welding welding process which ensures the continuous production of 300 series stainless steel. Background technique [0002] Stainless steel has very strict requirements on the surface quality. When working on the annealing and pickling line, the most taboo is the sharp decrease in the speed of the process section, which will cause over-annealing of the strip steel in the annealing furnace, resulting in over-acid production of the strip steel in the subsequent pickling section. Cleaning and pollution defects; production line stoppage has the greatest impact, so it is very important to ensure good inlet weldability and continuous and stable operation of the production line. Therefore, the welding machine is the key equipment to ensure the continuous production of the stainless steel plate annealing line, and...
