Resistance welding argon arc shielded welding combined welding machine

Abstract

The invention discloses a resistance welding argon arc shielded welding combined welding machine. The resistance welding argon arc shielded welding combined welding machine comprises an operation sideand a transportation side; the operation side is provided with a vehicle frame, a resistance welding component, a double-blade shearing component and an argon arc welding component; the transportation side is provided with a centering conveying component, a crescent shearing component and a punching component; the resistance welding component comprises a rolling wheel, an electric welding wheel,a lifting device and a heating device; the argon arc welding component comprises at least one argon arc welding gun, an upright post and a moving component; the centering conveying component comprisesan inlet clap, an outlet clamp, a front centering sleeve picking element and a rear centering sleeve picking element; the rear centering sleeve picking element comprises two groups of centering parts; and the crescent shearing component and the punching component are arranged between the two groups of centering parts. The resistance welding argon arc shielded welding combined welding machine disclosed by the invention can be used for implementing different forms of welding according to strip steel different in thickness, lowers the equipment investment cost and the labor cost in a strip steelproduction process, eliminates the stress of a welding seam, improves the quality of the welding seam and meets the technical requirements of welding of the strip steel.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a hybrid welding machine for resistance welding and argon arc shielded welding. Background technique [0002] As one of the important equipment in the pickling process of strip steel, welding machine is to quickly connect the tail of the previous strip steel to the head of the next strip steel, so as to realize the continuous production of steel pickling process and improve the production efficiency of strip steel . [0003] The traditional resistance welding machine is generally only suitable for welding thin plates with a plate thickness of 0.3-1.2. A large current is passed in between, and the upper plate and the lower plate form a melting zone under high resistance heat, and are rapidly cooled to form a weld to quickly connect the upper plate and the lower plate. Traditional argon arc welding machines are generally only suitable for welding plates with a thickness...

AI Technical Summary

Problems solved by technology

[0004] If the traditional welding machine is used, for the production line of a steel mill with multiple specifications and a large thickness range, resistance welding machines, argon arc welding machines and their supporting production lines need to be equipped at the same time, which increases the equipment cost and worker management cost of the steel mill

In addition, some people at home and abroad try to weld the strip steel by using a combination welding machine of resistance welding and argon arc welding, but the quality of the weld seam is average, and it is easy to form stress concentration at the weld seam, causing problems such as fracture, which affects the further development of the strip steel. processing
