Welding device and welding equipment with same

Abstract

The invention discloses a welding device. The welding device comprises an induction heater and a welding gun assembly, wherein the induction heater and the welding gun assembly are sequentially arranged on a connecting component in a first direction; a heating end of the induction heater and a welding head of the welding gun assembly are arranged in the same direction relative to the connecting component; and the first direction is a welding joint forming direction. According to the welding device with a function of preheating before welding, welding quality can be effectively controlled on the basis that operation time is effectively shortened; and meanwhile, due to the fact that preheating and welding operations are synchronously carried out, waiting time between the preheating and welding operations is eliminated, so that production efficiency can be effectively improved, and an energy utilization rate is higher. In addition, the induction heater utilizing the electromagnetic induction principle is adopted in the technical scheme, so that splash cannot occur in a heating process, security accidents, such as burn injury, scald injury in an operation process can be eliminated, production safety of operators is guaranteed, and operating environment is greatly improved. On this basis, the invention further provides welding equipment with the welding device.

Description

Technical field [0001] The present invention relates to the technical field of welding equipment, in particular to a welding device and a welding equipment with the device. Background technique [0002] With the rapid development of economic construction, the scale of infrastructure such as road traffic, airports, ports, water conservancy and hydropower, and municipal construction has also become larger and larger, and the demand for various types of construction machinery has gradually changed in a trend of high load. In addition to power systems, control systems, etc., the load-bearing capacity of the construction machinery body needs to be improved simultaneously, and the welding quality of its main load-bearing structural parts has become one of the important indicators to meet high load requirements. [0003] As we all know, the welding of important components and thicker parts requires preheating before welding to obtain higher welding quality. In the prior art, preheating b...

AI Technical Summary

Problems solved by technology

The randomness of manual operation makes the preheating width of the weldment and the moving speed of heating not constant. At the same time, there are temperature differences in the successively heated areas, resulting in joint deformation and uneven stress distribution after welding.

[0006] (2) Poor economy

When preheating large structural parts, due to the existence of heat conduction, heat radiation, convection and other phenomena, most of the heat will be lost; and the heated workpiece will also lose heat due to untimely welding, and the energy utilization rate is low. , poor economy

[0007] (3) High requirements for manual operation experience and low work efficiency

[0008] (4) Poor working environment

The spatter generated during the heating process is easy to burn the operator
