Final answer:
Some possible problems associated with high temperatures in welding include eye damage, thermal stress leading to cracks, and the production of chemicals that may increase cancer risk.
Step-by-step explanation:
Welding involves high temperatures that can pose several problems. One potential issue is the emission of high-energy electromagnetic radiation, such as UVB light, which can cause damage to the eyes and lead to conditions like welder's flash and cataracts. Another concern is thermal stress, which can contribute to cracks and failures in welded structures. Additionally, high temperatures during welding can produce chemicals that may increase the risk of cancer.
