root penetration | WELDING ANSWERS
W hen weld sizes are determined by design engineers, the theoretical throat is used to calculate weld strength which in turn gives our leg size (for fillet welds). This means that the desired strength of a weld is achieved only if we attain fusion to the root and side walls. The terms fusion and penetration are used […]

2024年3月6日 · M any fabricators can lower their welding costs significantly if they paid close attention to weld sizes. If a print calls for a ¼” fillet weld and in production you make a 5/16” fillet weld, you are overwelding by 56%! If the print calls for a 3/16” fillet, the 5/16” fillet weld you deposit would be […]
Welding Cost Reduction Revisited - WELDING ANSWERS
Some codes may allow up to a 1/16″ gap on fillet welds. Anything more than that and your fillet weld leg size must be increased by the size of the gap. Increasing a 1/4″ fillet to 3/8″ represents a huge increase in fillet metal needed.
5 Common Mistakes Made When Estimating the Costs of a …
Overwelding – If you are to make 100 feet of 3/16-inch fillet welds that would require 5.99 pounds of weld. metal If the weld size is not controlled and typical welds made in the shop are ¼-inch that would mean an increase of 78% in filler metal required. So instead of 5.99 pounds you will need 10.65 pounds of weld metal.
Should Heat Input Always Be Kept As Low As Possible?
2019年12月12日 · This is the reason why the structural welding code for steel (AWS D1.1) has minimum fillet weld sizes. For further details on this read The Reason behind Minimum Fillet Weld Sizes . Welding thick sections – the higher heat input will help with penetration provided the travel speed is adequate for the deposition rate of the welding procedure.
What To Do When Welding Codes Are Not Clear
2022年9月29日 · For example, the Design Clause of AWS D1.1 states that for lap joints where the metal thickness is ¼-inch or greater there is a maximum fillet weld size equal to t – 1/16-inch, where t is the thickness of the base metal, as shown below.

2023年7月26日 · H ave you ever noticed that there are design rules that prohibit sizing a fillet weld below a certain size for a given thickness of material? If you look at AWS D1.1/D1.1M:2020 Structural Welding Code (Steel) you can find this on Table 7.7.
