weldment design 04 - product design rules

Welding may be imperfect and there's a million ways to overcome the distortion, but the best thing to do is considering the product's design carefully so that the effort on manufacturing is kept minimum
Just like plastic molding and sand casting, each welded product must be designed thoroughly according to the process they had to undergo. There is still some chance the distortion would happen, but on a straight line of procedures and a wise design, it wouldn't spend too much energy compared to a harshly designed ones.


Here are some considerations you need to put on your welded product : 
> For same strength, longer leg size cost more. Use smaller leg size with longer length.

 > Use Symmetric sections for Automatic welding

> Design Simple. Save Welding cost

> Use minimum amount of weld metal

> Easy accessability to welding

> Arrange the welding layout which would reduce welding cost

> Under light load, use intermittent weld in place of continuous weld
> Weld in the section with least thickness

Like i said before, a proper planning wouldn't hurt
