Question 1

When manufacturing fused fluxes, the temperature at which the ingredients are melted together is:

Answer 1

1,500C to 1,700C

Question 2

Bonded fluxes have a lower density then fused fluxes, and therefore less flux is consumed during welding. the percentage difference in flux used during a typical application is:

Answer 2

20%

Question 3

When improved mechanical properties (toughness) of the weld metal deposit is required, the flux should be formulated to transfer the smallest possible quantity of:

Answer 3

oxygen

Question 4

An electrode with the designation FS48P3-EL8K represents an electrode/flux combination that has:

Answer 4

been classified in accordance to ASW A5.17M
