Abstract

We have compared with welding workability, mechanical properties and crack sencitivity of deposited metals, for trial production and market austenitic electrodes.
The results are as follows :
1. Titania type coated austenitic electrodes has good welding workability compared with lime type.
2. Low ratio of silicon content to manganese content, low ratio of sulphur content to manganese content and low phosphorous content in deposited metals is desirable to prevent the weld metal hot cracking.
3. Trial production fully austenitic Ni-Cr-Mn (12-20-8) electrode has good welding workability, mechanical properties and crack free welds.
4. Trial production austenitic. Mn-Cr-Ni (17-17-5) electrode has good weldability too.
5. Tezuka type slit test has excellent characters for the crack test of welding electrodes.
