Welding Consumable Content – For Steel Structures Typical of the Process/ Chemical
While each steel fabrication project is unique and to generalize in the form of a
welding consumable content rule of thumb carries with it a greater degree of uncertainty,
it is nonetheless sometimes necessary in the absence of either data or time.
Generally for large steel structures such as that of the process/ chemical industry
using 2.5% to 3% of welding consumable content per total steel structural weight
would normally be sufficient.
For example to calculate the cost (via the weight of) the welding consumable content
of an oil and gas jacket, piles and topside with a combined structural steel weight
of say 2,500 tonnes, the formula would be as follows:
