The question of the day is can you weld thick metal? And yes, you absolutely can. How to Weld Thick Metal вЂ“ The Complete Process So, no you canвЂ™t weld that thickness in a single pass but you can weld that thickness with other methods. The chart is a guideline for welding in a single pass. You should take on the challenges of thicker materials by understanding that you will need to use multiple passes at maximum power.ДonвЂ™t assume that because your chart says you canвЂ™t weld a 1/2-inch thickness that you truly canвЂ™t. What it means is that is the maximum thickness you can weld in a single pass вЂ“ there is a difference, and understanding that could allow you to weld substantially thicker materials. That doesnвЂ™t mean you canвЂ™t weld any higher. 001вЂі of metalДЇor example, the chart might say that 230 volts (roughly 210 amps) can weld 3/8вЂќ thickness. Metal Thickness Amperage 1/8вЂі Mild Steel 125 Amps 1/4вЂі Mild Steel 250 Amps 3/8вЂі Mild Steel 375 Amps 1/2вЂі Mild Steel 500 Amps 1 amp per. The chart tells you what amperage to use for what thickness and even tells you what maximum thickness your welder can accommodate based on the amps.
