WEL 2035 - Shielded Metal Arc Welding

• Demonstrate the ability to strike an arc at a specific point 

• Describe the terms work-angles and travel-angles and the effects of those electrode angles for proper bead formation 

• Interpret and troubleshoot problems that result from welding current being too high or too low 

• Identify and select the proper size and class of welding electrode for a given application
