Welding Cracks

Welding Cracks: Hidden Causes & How To Stop Them 2026

Welding cracks are fractures or discontinuities in weld metal, heat-affected zone (HAZ), or base metal that compromise weld integrity and structural performance. These critical defects can lead to catastrophic structural failures, requiring 100% repair in code work and causing significant economic impact through rework and delays. After spending 15 years in fabrication shops and witnessing

TIG Welding

What is TIG Welding? The Complete Beginner’s Guide

TIG welding stands out as the most precise welding method available today. It produces clean, beautiful welds that look almost factory-made. TIG welding (Tungsten Inert Gas welding), also known as GTAW (Gas Tungsten Arc Welding), is a precise arc welding process that uses a non-consumable tungsten electrode and inert shielding gas (usually argon) to create

Titanium Welding

Titanium Welding: Complete Guide for 2026

Titanium welding is the process of joining titanium and its alloys using TIG (GTAW) welding with extensive argon gas shielding to prevent atmospheric contamination. Yes, titanium can be welded successfully, and it’s actually easier to weld than many metallurgically complex metals like some stainless steels. The main challenge isn’t the welding itself, it’s contamination control.

Plasma Arc Cutting

What is Plasma Arc Cutting? Complete Guide to Plasma Cutting Process

Plasma arc cutting is a thermal cutting process that uses an accelerated jet of superheated, electrically ionized gas called plasma to cut through electrically conductive materials. The process works by forcing compressed gas through a constricted nozzle while an electrical arc forms between an electrode and the workpiece, ionizing the gas into plasma that reaches
