AI Technical Summary

Technical Problem

Traditional welding cooling technology has problems such as uncontrollable cooling rate, deformation and cracks caused by thermal stress gradients, water cooling can easily cause local embrittlement of materials, and insufficient air-cooled cooling stability, making it difficult to ensure welding quality and structural performance.

Method used

A cooling equipment for welding metal building materials was designed. The introduction device was used to drive the gasified nitrogen into the heat dissipation shell through the ventilation duct. The nitrogen was cooled overall through the side of the welding device. Combined with the arc-shaped phase change box and the piston tube system, the gas flow rate was dynamically adjusted to different areas and improved heat dissipation efficiency.

Benefits of technology

It realizes efficient cooling on the sides of the welding device, reduces the temperature difference in the welding area, avoids material embrittlement and deformation, and improves welding quality and structural performance.

Abstract

The invention relates to the technical field of welding equipment, and particularly discloses cooling equipment for metal building material welding, and the cooling equipment for metal building material welding achieves the purposes of cooling a workpiece and carrying out gas protection during welding. The heat dissipation device dissipates heat generated in the welding device, so that the working state of the welding device is stabilized, long-time work is facilitated, gas is guided into the surface of a workpiece through the pipeline design of the heat dissipation device, and therefore the welded workpiece is rapidly cooled; due to the fact that the temperature rises after heat is transferred through the surface of the welding device, the temperature difference between the gas temperature and the workpiece is reduced, workpiece embrittlement caused by too fast cooling is avoided, the heat dissipation device blows the surface of the workpiece in a targeted mode, compared with a traditional gas protection mode, the using amount of nitrogen is reduced, the workpiece is self-locked and fixed through the fixing device, and the welding efficiency is improved. And welding errors caused by shaking of the workpiece during welding are prevented.
