Co2 welding defects FTA (fault tree analysis) Report.

Fault tree analysis for CO2 welding defect

The process of joining two metals is carried out by the welding process. The welding process is carried out by generating high temperatures at the joining area by using a high current voltage ratio. Welding may be carried out either by spotting, CO2 Weld, or any other welding process. In this blog, we will focus on how CO2 Welding is carried out. What are the requirements of good CO2 Welding? What are the parameters that affect CO2 weld quality by performance and aesthetic way? 

When we have to weld two metal parts there we require a specified proportion of voltage and current ratio as per our requirement set during our pilot batch. Also, wire use as filler metal should have diameter and copper coated as per set during the pilot batch. Also, gas used during the welding process for a better quality of the weld is also to be in decided proportion 80/20 ratio or 90/10 ration of oxygen and carbon dioxide as it affects the quality of welding. Wire feed rate is also to be set one time during the pilot batch and should get follow every time. Gas flow rate also to be as per set during the pilot batch. Also, the operator who is doing welding is matters for good weld quality. The operator should get trained well before putting him on daily production activities. He should know the torch angle to be used during welding. He must be aware of the required voltage-current ratio and can able to change any pandemic situation. He must be aware of safety precautions to be taken during welding.

These precautions to be taken if we are expecting good welding quality to defined productivity. Now we will see defect we will go e face if we didn't follow standard specification set.

After that, we will see FTA analysis for all of those defects.
