Products supplied by EV Group China are designed to ensure high-quality welded joints when using TIG (tungsten inert gas welding), MIG (gas metal arc welding), and plasma welding methods. The use of materials that comply with the standard guarantees stable physical and mechanical characteristics of the weld.<\/p>\n<h2>Classification System for Filler Materials<\/h2>\n<p>The classification of welding materials according to the AWS A5.16 standard is not tied to a specific system of measurement units, which ensures versatility of application. It is based on strict control of the chemical composition, as presented in the table below. Experts at EV Group China emphasize that the chemical purity of the alloy is a decisive factor in preventing metal embrittlement in the heat-affected zone.<\/p>\n<table class=\"table table-bordered table-hover\">\n<thead>\n<tr>\n<th>AWS Classification<\/th>\n<th>Chemical Composition (Main Elements)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>ERTi-1<\/td>\n<td>High-purity titanium<\/td>\n<\/tr>\n<tr>\n<td>ERTi-2<\/td>\n<td>Commercially pure titanium<\/td>\n<\/tr>\n<tr>\n<td>ERTi-5<\/td>\n<td>Ti-6Al-4V (titanium alloy)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Filler metals certified under this classification are mutually exclusive, except in cases where the chemical compositions of the grades fully correspond.
