Re: [MW:14229] How to tack weld the screen to frame successfully

By Materials & Welding
你好。
你的英文，我还是猜着看的，大致懂了。。。per (as per)。。。
你既然是TIG焊，肯定用焊材了，你第三点without filler metals是什么意思？
你的网格线是什么规格？
如果用的焊材，是什么规格？尽量选择细丝ER308L，如0.8mm、0.9mm、1.0mm的。
是不是每个节点都有焊？有强度要求么？ - 如果这样，可以考虑钎焊 brazing

Dear Experts,


We are preparing to tack weld weir screen to frame per design specification. And We find that,Once welder start the arc using the GTAW(TIG) and move it near to the joint between the screen wire and the frame, the wires fuse instantly and break ,even we adopt the minimum current .

1.Wire Diameter：1.2mm

2.Material: 304L stainless

3.Process: GTAW without filler metal.

 

Any suggestion or comments will be grateful.

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

Re: [MW:10788] ON PLOT PIPING & OFF PLOT PIPING

By Materials & Welding
Piping systems involved for the flow lines and gathering lines from the well head isolation valve to the production facility or processing plant isolation valve are determined as OFF PLOT. ON PLOT defines piping system in the processing plant and production platform. ANSI/ASME B31.4 applies for off plot piping system. B31.4 allows the use of either API 1104 or ASME section IX (as appropriate). However, occasionally, a very small system such as piping within 500 feet of a processing plant (some client also said 400 feet) may be declared B31.3 rather than B31.4. When B31.3 is invoked, only ASME Section IX is used. before you decide which code to use for welding procedure and/or welder qualification for pipe welding, you have to know the design and construction code applicable to the system. Please read far enough into scope and diagram illustrating the application of either B31.3 and B31.4 hope this helps rgds 2011/4/21 pradip kumar sil < pradipsil@gmail.com > Dear all, ...
