The invention discloses a method for producing stainless steel welded pipes with patterns, which is characterized in that floral patterns with clear lines are rolled on the surfaces of the stainless steel welded pipes and the production efficiency is high. The method comprises the following steps: heating the stainless steel strips with intermediate frequency heating coils under the protection of mixed gases of hydrogen and nitrogen; carrying out continuous production and discontinuous engraving by a three-roller type asynchronous engraving hot mill; and cooling the stainless steel strips which exit from a rolling mill and have single surfaces engraved, rolling roughly molded horizontal roller sets into drums and welding the drums into circular pipes with a stainless steel pipe welder, wherein the horizontal rollers in the horizontal roller sets are made of MC nylons or rubber materials; an upper roller of the rolling mill is a drive engraving roller, a medium roller is a driven plain work roller and a lower roller is a drive plain backup roller; the engraving depth is 0.2-2.7mm; the external diameter ratio of the upper, medium and lower rollers is 1:0.2-0.4:0.8-1; and the speed ratio of the upper and lower rollers is 1:0.6-0.9.
