Re: [MW:24388] RE: 24384] Welding by SAW process is it mandatory for heavy thick vessels in H2 service

Hi 
I have seen SAW process in horizontal position at site during construction of tanks. Hence SAW is possible.

Hi friend,

 

There is no restriction to SMAW. (subjected to a qualified WPS)

Better you show the setup requirement for SAW to the client and let him understand, hope he will get convinced,.

 

 

Thanks & Regards,

Dear welding experts,

 

We are manufacturing heavy wall vessels for H2 service.

MOC SA 516 Gr 70. Thick 56 mm

Due to large size vessels are to be supplied in two sections.

Hence on site weld joint will have to be done at place of installation.

At shop we are using SAW process for welding.

At field rotating is not possible and we want to use SMAW process.

Our client is asking us to use SAW process for field weld joint also.

 

We know that SAW is semi automatic & more productive process.

 

My question is whether is their any restriction to use SMAW process.

 

Request experts to give their valuable views to convience client technically.

 

Best regards,

 

Prasad Ghanekar

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...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

By Materials & Welding
Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
