Apr 02, 2020 · Groove weld vs. fillet weld. In steel erection, completing high-quality welds with as little rework as possible is a critical part of maximizing productivity, along with keeping projects on schedule and within budget.. On structural jobsites, though fillet and groove welds are both used, fillet welds are the most common. The strength required for the application typically determines when a
JIS G3101 SS400 Mild Steel Plate and Q235B S235JR Sheet SS400 Mild Steel Cr Plates covers carbon structural steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes. ASTM MS SS400 Chequered Plate heat analysis shall be used to determine the required chemical compositions of carbon, manganese
QUALITY STANDARDS FOR STRUCTURAL WORKS1c Welding 1) Weld size, length and profile shall meet the structural steel specifications and drawings 2) Visual inspection shall meet the structural steel specifications 3) All weld shall follow approved welding procedures 4) All welding must be done by qualified welders 1d Bolting 1) Bolts and washers, type, size and number shall be
For the most part, the tolerances for welded members are the same as those for rolled members produced under ASTM A-6, even though rolling mill practice has only limited direct bearing on welded built-up members. One particular tolerance require ment to insure structural integrity involves the tilt or out-of-square limits for flanges.

This is because a large amount of steel used in fabricating a metal structure is low Carbon or plain carbon steel (also called mild steel). When welding these steels with any of the common arc welding processes like Stick Mig or Tig there are generally few precautions necessary to prevent changing the properties of the steel.

fillet welds tolerances - American Welding SocietyFeb 11, 2007 · Basically if you have a 5/16" weld 10" long, a total of 1" of that weld is allowed to be 3/16". You can undersized 10% of a 3/16" or less weld by a 1/16" or less and a 1/4" weld by 3/32" or less. Anything weld over 5/16" is allowed to be undersized by 1/8" or less as long as the undersized part of the weld does not exceed 10% of the total
Apr 04, 2012 · I am looking for a good source to define recommended tolerances for welded steel fabrications (large steel flood gates), something I can cite in the project specification I am writing to impose practical limits on the final product. You are talking about structural steel. This would be a good question to post in forum507:Structural
