How to calculate the K value of the weld leg in the fillet weld joint diagram
Thread Content
Our company’s welding engineer said that the K value should be equal to that of the thin plates on both sides; in other words, the K value in the diagram above should be 35. However, according to the standards, it only needs to be at least 0.15 times 35. So I would like to ask how to determine this K value
It is generally based on the thickness of the thinner sheet
It is generally quite thick; there is no need to consider the thickness of thin sections, as long as the strength is sufficient. Reference can be made to Appendix D of GB/T150.3
