Abstract

The invention relates to the technical field of welding tools, in particular to a welding backing suitable for fillet joints and a flux method. The welding backing includes: an elastic support structure, which is suitable for being arranged at the reverse grooves of two workpieces to be welded to support the The flux filled at the groove on the reverse side; the fixed structure is connected to the elastic support structure through the connecting structure, and the fixed structure has a mounting surface for detaching and connecting with the two workpieces to be welded. The invention provides a welding pad suitable for fillet joints which is firmly connected with workpieces to be welded and a welding method.

Description

technical field [0001] The invention relates to the technical field of welding tools, in particular to a welding pad suitable for fillet joints and a welding method. Background technique [0002] The full penetration welding technology uses manual welding or submerged arc welding to make the bottom, and then adopts the method of carbon arc gouging on the supporting surface. This method will bring arc light, smoke, noise and other environmental pollution when using carbon arc gouging. , causing great harm to the workers' bodies. The longest working time of workers in the clearing job should not exceed one year, otherwise it will cause deafness; in addition, due to the excessive smoke and dust during root clearing, workers are prone to pneumoconiosis; the use of carbon arc When gouging, it consumes a lot of manpower, equipment, etc., and increases the amount of welding material filling and energy consumption; when using carbon arc gouging, it is easy to cause large deformation...
