2013年10月24日 · I suppose that the hole does have a radius or "rad" to it. However, I suspect that the person detailing the steel has never seen the word written previously. In my experience, the weld access hole(s) for a butt welded beam splice look very much like the holes made by rodents therefore I call them "rat" holes.

2012年5月15日 · Depending on the intended connection type, the requirements may very. In general a weld access holes is required for flange welded moment connections. In additional to access, weld access holes provide ductility and improved performance of moment connections Also it is impossible to provide complete penetration welds in the center at the beam web.

2013年6月12日 · In figure 5.2 for rolled sections the weld access hole for the top flange is shown as coming off the flange at an angle all the the way out from the point of the groove. If this is done the backing will not fit flush with the bottom of the flange. Is it …

2009年11月12日 · Hello, guys, I am a Graduate engineer based in the UK and currently working in China for one power project. The problem I am facing now is about "Welding Access Hole" at Fillet Welded Shape component as shown in Figure 5.2 on AWS. According to AWS 5.17, "Fillet welds shall not be returned...

2009年5月11日 · CJP weld of the flanges, which should provide a weld access hole (not shown) for backguoging access and welding. And fillet welds for the web/bottom flange. An SWPS is available for the B-U4b. And the fillet welds are a separate welding procedure for which a WPS is easily written. SWPS's are available for many of the weld details shown in D1.1.

2006年5月4日 · The discussion has yet to produce a viable solution in our situation and without access, the backing cannot be removed. Therefore a one-sided weld is not allowed by the Bridge Welding Code. In addition, PJPs are also prohibited by AASHTO. As a possible solution, access holes for construction of the box are possible.

2011年10月21日 · Weld access holes should be provided. In addition to providing access for a continuous backing bar, weld access holes increase ductility and aid in reducing stress concentrations. If beam web connections are field welded as well, the web welds should be completed after the flange CJP welds are completed and cooled.

2017年8月18日 · The copes in those cases do not utilize the access hole details shown in your figures. They are unnecessary. If CJP groove welds are unnecessary, if sufficient access is provided to weld from one side, where PJP does not necessitate the need for a backing bar, there is no justification for the access hole. Best regards - Al

2010年3月29日 · On large girders or heavy welds, I would weld on both sides of the web at the same time, again to control welding distortion; this will tend to keep the flange at 90° wrt the web. This t&b alternating will minimize the camber (weld distorion) in your final beam.

2010年3月4日 · I seem to have misplaced my references for detailing a Weld acces hole ("rat-hole") for a full penetration weld for the flange of a wideflange beam.
