CJP Weld Spacing

CJP Weld Spacing

CJP Weld Spacing

(OP)
Are there guidelines on minimum spacing of CJP welds? I'm looking at a submittal of a truss chord 1100 mm deep with two CJP butt weld splices 460 mm apart.
Thanks!

RE: CJP Weld Spacing

What is the difference between a multipass groove weld where the weld beads are fused together and two groove welds that are nearly side by side? There is little to no difference if one is welding low carbon or high strength low alloy steels that have no toughness requirements. Generally, notch toughness is not a concern if the steel framing is enclosed by the building envelop and where the design is not subject to seismic activity or impact loads.

RE: CJP Weld Spacing

Why would they splice a chord twice that close together?

RE: CJP Weld Spacing

Some one cut it twice and it was still too short?

RE: CJP Weld Spacing

Well, what do you do when you have a truss 81 feet long, and the longest plate you can get is 40 feet? Just saying, it's not always an error by the fabricator.

Thank you all!

Engineering Report - Top 10 Defect Types in Production
This 22-page report from Instrumental identifies the most common production defect types discovered in 2020, showcases trends from 2019 to 2020, and provides insights on how to prevent potential downtime in 2021. Unlike other methods, Instrumental drives correlations between a variety of data sources to help engineers find and fix root causes. Download Now
White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
