Read the welds on an assembly
One drawing, three welding symbols, five questions about it. Then a new drawing. Get 10 right to finish.
Same drawing, question 1 of 5
On which side of the joint is the weld between the gusset and the post?
How to work through a drawing
- Find the joint the question is about: post to base plate, gusset to post, or gusset to base plate.
- Follow the arrow that touches that joint back to its reference line.
- Read only that symbol. The other symbols on the sheet are for other joints.
Some answers have to be worked out, like the gap between intermittent welds or the leg size for an ISO throat size. Type those as a number. Each drawing gets five questions, so you read it the way you would read a print at work.
Questions
- How do I read several welding symbols on one drawing?
- One symbol at a time. Follow each arrow to the joint it touches, then read that symbol in full: side, size, length and pitch, all around and field weld.
- Which welds are made on site?
- Only the ones whose symbol has a flag at the bend of the arrow. Every other weld is made in the shop.
