Abstract

The invention relates to preheating welding equipment. The preheating welding equipment comprises an arc welding machine and a movable platform. The arc welding machine is arranged on the movable platform. The arc welding machine and the movable platform are connected through a connecting arm. The connecting arm is further connected with a multi-head heating torch. The arc welding machine and themulti-head heating torch are arranged in the same axial direction, and the multi-head heating torch is connected with an air linkage pipe. The preheating welding equipment has the beneficial effects that the arc welding machine and the multi-head heating torch are arranged in the same axial direction, high efficiency and safety can be achieved, management is convenient, input is little, the preheating welding equipment can conduct synchronous construction with welding, the high-strength steel welding preheating requirement is met, and accordingly the welding technology and welding quality requirements are met.

Description

technical field [0001] The present invention relates to a preheating welding equipment, in particular to a preheating welding equipment for steel plates, and also relates to a welding and using method of the preheating welding equipment. Background technique [0002] In the design of steel structures, in order to meet the structural load-bearing requirements, a large number of thick and high-strength special steels are used. These special high-strength steels are prone to cracks and other defects during the welding process, which will affect the structural strength. Therefore, it is necessary to preheat at a certain temperature before welding to avoid defects, and to heat after welding to ensure the quality of the weld structure. No matter the traditional heating method adopts conduction or radiation heating, it is heated before welding, and then the welding construction is carried out after removing the heating device. In this way, the efficiency is very low and the heatin...
