The most common problems are burn-through, atmospheric contamination, and inadequate penetration. Burn-through (as it's name suggests) is when the metals become too hot and create holes or gaps in the weld joint. Burn-through is most often caused by excessive power through the arc. Atmospheric contamination (most commonly oxidization) occurs when there is not enough shielding from the air to protect the weld and atmospheric gases bond to the metal and weaken the weld. Inadequate penetration is caused by insufficient power in the arc resulting in a temperature too cool to effectively join the metal together.

What is the importance of welding in engineering?
There is a tremendous importance of welding in engineering, there are even such things as welding engineers ( I am one). Welding is what holds the majority of structures together--bridges, cars, tractors, cranes, buildings, etc...If any engineer does not have a good understand of this very popular joining process major problems can exist, such as failures from designing a joint that is un-weldable. Most companies these days are trying to hire welding engineers to help with these problems. Welding can get very specialized with more technical metals and applications.
How do you troubleshoot the porosity blow holes burnthrough problems in CO2 MIG welding?
Check the shielding gas & its flow rate.
What is the welding cert roster code for welding?
roster welding
Name of the type of welding?
One type of welding is tube welding. Another type if mig welding.
Difference between ERW and SAW welding?
SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.

What are the problems that can occur with the welding activities and how these can be overcome?
Many problems can be experienced in welding including cracks, infusions and distortion. Generally these can be avoided by eliminating hydrogen, keeping temperature under control and controlling the atmospheric pressure of the environment.
