Appreciation post: The old-timer who changed my mind on pre-heating thick plate

I used to skip it on anything under 2 inches, but after seeing his crew's welds on a 2.5-inch pressure vessel in Baton Rouge, I'm a full convert. What's your go-to pre-heat method for heavy sections?

My old foreman used to call my no-preheat habit "wishing on a star." He finally got through to me with a rosebud torch on some 3-inch jig plate. Now I just accept the extra time.

Ever try to weld cold plate and just make a sparkly mess instead?

My first boss caught me trying to weld 1-inch cold and just laughed for a solid minute. @jessica331, I know that sparkly mess all too well... I'm a rosebud guy now too, no matter how much I grumble about it.
