[Chris18]

Hello guys. In the picture below can u help me with the problems! I cannot understand what exactly should I comment about the strengths. I t would be easier if it was asking about the types of welding :) . Please give some help! Thanks in advance!

They are convex, concave and mitre (or straight) welds on a lap joint.
The most important difference is the effective throat.

This should give you some search terms for your textbooks/lecture notes/Google.

Less sharp edges, less stress load. I would say 3rd one is more strong at first glance.

You need to do a bit more investigation as to why the above prior post statement is important.
