Corby Sirkel is one of the elite welders, having welded on every continent except Antarctica — from the 114 ambient temperatures in Egypt, to the inner bellies of the gold mines in Perth, Australia. He has no formal welding education and no college degree, but his passion to be the best has taken him to unimaginable places in a trade most outsiders know nothing about. He started in concrete and realized quickly he didn't want that forever — though he'll be the first to admit that between the frigidly cold winters and the long hot summers, it made a man out of him. Today, Corby is the Global Technical Services Engineer for Epiroc Drilling Solutions.
