Problems solved by technology

However, due to some questionable problems in the welding principle, method and mechanical structure, the welding quality of the overlapping joints of the steel grating products produced by these automatic pressure welding production lines is low, and there are serious problems such as twisted square steel falling off, flat steel falling off, etc. Phenomenon; the welding quality of lap joints is essentially a virtual weld with very weak bonding strength and only limited local mechanical hooking
These pressure welding production lines also generally consume a lot of electricity, which is incompatible with the country's energy policy
It also increases the production cost of the product

Abstract

A pressure welding method and apparatus for the grated steel plate features that multiple individual welding transformers are used to supply electric power, the individual upper electrode cluster is used, and the flat steel is used for lateral conduction of electric power. Its advantages are low electric consumption decreased by 90%, and high welding quality and accuracy.

Description

technical field [0001] The present invention relates to the pressure welding method and equipment of the so-called steel grid plate, the steel grid plate is used as a platform for ironmaking blast furnaces, power plant boilers, chemical tank towers, oil production platforms, seaport docks, workshop floors, and used as a filter fence for Sluice, ditch well cover; can also be used for guardrails, screens, etc. The invention provides a manufacturing method and production equipment for the steel grating. Background technique [0002] Steel grating is a new type of building material that has appeared in China in the past ten years and has been rapidly expanded and used. With the advantages of high structural strength, light component weight, steel saving, and convenient installation, it has emerged as an irreplaceable building material in the terrace structure and wide areas. [0003] The structural type of steel grating is as follows: figure 1 As shown, the load-bearing flat ...
