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

Before talking about DC+ and DC-,First, we need to understand the definition of DC welding machine connections. In China, the Base metal is used as the reference: when the workpiece is connected to the positive terminal, it is called DC positive polarity (DC positive connection); when the Bease meta
