PURPOSE: A handle coupling method of a cooking container is provided to prevent foreign material from being caught on the sidewall of the container in a cooking process by coupling the handle using a spot welding method which does not penetrate the sidewall. CONSTITUTION: A handle coupling method of a cooking container includes the following process steps. A welding assembling groove is drilled on the outer surface of the container(ST1). A rivet which is combined to a flange is inserted into the welding assembling groove(ST2). A spot welding is performed on the end of the rivet(ST3). An argon welding is performed at the flange(ST3-1). A handle with a through hole is attached on the rivet(ST4). A protruded end of the rivet is pressurized and a head is formed, thereby preventing the handle from separating(ST5). |
