Welding Methods and Precautions for Galvanized Steel Pipes
Galvanized steel pipes are increasingly widely used in water supply and drainage, fire protection, heating, ventilation, and industrial transportation fields due to their excellent corrosion resistance, long service life, and cost-effective advantages. However, the welding process of galvanized steel pipes is special. The galvanized layer on the surface is prone to melting, evaporation and other reactions under the high-temperature welding environment. If the operation is not standardized, it is likely to cause defects such as porosity, cracks, and slag inclusion in the weld. This will not only reduce the joint strength and tightness, but also may shorten the overall service life of the pipe and even cause potential safety hazards. To help relevant practitioners master scientific welding technology, avoid construction risks, and ensure project quality, this article will systematically sort out the core points and precautions of galvanized steel pipe welding from key links such as pre-welding preparation, characteristics of galvanized steel pipes, process control, and operating techniques.

In June 2025, the inspection report of a fishery-photovoltaic complementary power station in Binzhou, Shandong Province, shocked the industry - the photovoltaic brackets built at the same time showed a polarization: the hot-dip galvanized steel brackets had obvious rust, the aluminum alloy brackets had slight deformation due to insufficient load-bearing capacity, while the brackets made of zinc-aluminum-magnesium materials were as clean and shiny as new! This case has exposed the "hidden pain point" in the photovoltaic industry: material selection is becoming a key variable in the revenue of power stations.

In road traffic safety facilities, the anti-corrosion performance of wave-beam guardrails directly determines their service life and protective effect. Spray coating and dip coating are the two most commonly used anti-corrosion processes for wave-beam guardrails. Although both use "plastic" as the anti-corrosion medium, they differ significantly in process principles, coating characteristics, applicable scenarios and other aspects. This article will deeply analyze the differences between the two from multiple dimensions to provide reference for relevant practitioners and purchasers.
