Re: [MW:32738] Requalification of consumable after shelf life

Just for info.

That is why Inventory control is very critical in Fabrication industry. You need to estimate the correct quantity and procure them. Moreover you quantify the welding consumable as stock items and critical items. Special consumable come under critical items and normal moving used items like carbon steel come under stock items.

If consumable after shelf life is small quantity then you can use it for welder training purpose else if it is a Large quantity then better to contact welding consumable manufacturer.

Thanks & Regards

Normally we do not use welding consumables beyond the Shelf life as recommended by welding consumable manufacturer. I have physically seen Flux coating peeling off from the electrode. It is better to contact the welding consumable manufacturer and if they recommend better to do consumable testing as per ASME Sec.IIC at the manufacturer's premises.

Thanks & Regards

Dear,

This is not possible and there is no direction on ASME section IX as it is solely part of the manufacturer, once shelf life finishes you can further use those electrodes.

Dear all,

Can we requalify  welding consumables (electrode and wires) once the shelf life is over.

As ASME code gives any guideline to requalify  the welding consumables.

Kindly provide your expert opinion on this.

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

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

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...
