How to choose the shielding gas in welding？Shielding gases are primarily categorized into inert gases (Ar, He), active gases (CO₂, O₂, N₂, H₂), and their mixtures.Mixtures are most commonly used in welding, as they combine the advantages of different gases to optimize welding performance.For Carbon

Stainless Steel Welding Wire: ER308, ER308L, ER308LSi and how to choose them?Core Difference: CompositionThe key distinctions are defined by two elements:Carbon (C): 'L' denotes Low Carbon (~0.03% max) vs. Standard (~0.08% max).Silicon (Si): 'Si' denotes High Silicon (0.65-0.90%) vs. Standard (0.30

ER4043 and ER4047 are both very common aluminum-silicon (4xxx series) welding wires, and their differences, while subtle, are crucial for specific applications.Here’s a detailed breakdown.The Core Difference: Silicon Content & Eutectic PointThis is the most fundamental difference that drives all oth

E6013 welding eletrode is acidic electrode or basic electrode? The E6013 welding electrode is an acidic electrode. Its coating is primarily based on rutile (titanium dioxide) and contains a significant proportion of acidic oxides like silica. How to distinguish acidic and basic welding electrode? 1
