looking for suggestions of aluminum welding

My old pontoon has created two small cracks about six inches in where the top meets the u shaped bottom. I live in Rockwall Tx. looking for someone that wont change me an arm and a leg.

Check with Mcgills in Lewisville. All sorts of welding reasonably priced.

Good, fast,cheap. pick two of the three. Jerry Moore 903-887-6523 in Gun Barrel is the best I know of, not cheap but real good.Worth the trip for satisfaction and quality.
He fixes my Xpress on a semi regular basis.
