The temperature rise of torches under various conditions were measured with thermocouples at several positions of each torch, tip positions relatively corresponding in each torch, as sown in Table 1.
The test results revealed that;
(a) Heat radiation from flame itself and base material was the principal cause of temperature rise.
(b) In Type II', the maximum temperature was found to be about 300°C. This type of torch is considered to be the most desirable in gas welding.
(c) Tip temperature could be risen up to about 500°C under some conditions, but "back fire" took place above this temperature.
(d) The tip temperature rises were classified based on tip material and style of torch.
