Adjacent to the molten metal is a area that reaches excessive temperatures, but does no longer
melt? - ANSHeat affected quarter
Heating, melting, and solidification (cooling) of steel go away us with two essential elements to
do not forget: - ANSMetallurgical changes and stresses and strains may be precipitated inflicting
distortion and feasible cracking
The price at which a lamp converts electric power into heat and light is given through: -
ANScurrent instances voltage
The gadgets of modern times voltage is: - ANSamps x volts = joules in step with second (or
watts)
The share of overall warmth strength that enters the plate is referred to as: - ANSEfficiency
Which welding method has the best efficiency? - ANSSubmerged arc welding ninety-99%
Which welding manner has the lowest performance? - ANSGas tungsten arc welding 20-50%
The power enter is an crucial parameter that pertains to the - ANSsize of weld, the width of the
HAZ, and the cooling time
In fashionable the higher the power input - ANSthe large the weld, the broader the HAZ, and the
slower the cooling price
The equal electricity enter may be achived with various combination of - ANSwelding present
day and pace
Increasing the current and velocity in share continues the energy enter and fillet weld size
regular however - ANSincreases the penetration
The charge of cooling in a given material will rely on 4 important factors: - ANSheat input to the
weld, thermal conductivity of cloth, plate thickness, and temperature of the plates (preheat or
interpass temperature)
Increasing the warmth will - ANSreduce the cooling rate
Doubling the heat enter for thick plates will - ANShalve the cooling price
For thin plate, doubling the heat enter will - ANSreduce the cooling charge four instances
