Some of the European ones look forged to me, others are TIG welded. Years ago one of the local manufacturers was arc welding them, while another were TIGing and then sandblasting them. The arc welded ones looked a bit agricultural, but there must be thousands of them at Nowra and they are clearly still holding. |
