In addition, the analyses of weld surface ripple and microstructure with three current waveforms have indicated that the high frequency wave group modulated by low frequency GTA welding has the advantage of both the low frequency in which the heat input of the weld pool is easily controlled and high frequency GTA welding in which the arc is energy—concentrated and stiff.

另外，通过对高频脉冲焊、低频脉冲焊、低频调制高频方波群焊不锈钢焊缝表面形貌分析表明，低频调制高频方波群焊综合了低、高频GTA焊的特点。

Moveover, the relationship between mixity angle and the strain hardening exponent of welded seam was also studied.

进一步对熔合线上含裂纹焊接接头的复合角Φ与焊缝应变硬化指数的关系进行了研究。

The value of mixity angles becomes smaller with increasing strain hardening exponent at the same load level .

在同一外加载荷下，接头复合角Φ随着焊缝应变硬化指数的增加而减小。

Commonly the measure taked is to add a lead-to shutter and a lead-from shutter.to remove keyhool. But the most challenge is that the keyhool can not be removed to the loop welding line. So RPT is the best way to settle it.

解决办法就是外加导入板和导出板消除&匙孔&；而环形焊缝搅拌摩擦焊遇到的挑战就是焊接尾端&匙孔&的消除，可回抽式搅拌头是唯一的解决方法。

NS-07 new stabilizing suspension The suspension, with new structure and connected with international technology is divided into construction vehicle and highway vehicle.

NS-07新型平衡悬架与国际接轨、全新结构的悬架，解决了推力杆易损、桥壳易变形、桥壳焊缝开焊等问题，同时降低了整车自重，具有良好的平顺性和行驶稳定性。

The round hit the side of the Panther's turret, penetrating it cleanly and tearing the opposite side out at the welded seams, throwing it back a few metres. During these tests the muzzle brake of the A-19 blew up almost killing Voroshilov. After this accident it was decided to change the muzzle brake to a 2-chamber design similar to that used by the Germans.

这发炮弹集中了豹式坦克的炮塔侧面，干净利落的击穿并将另一侧的装甲沿焊缝撕裂，抛出了几米远，在测试中A-19炮口制退器产生的暴风差点杀死了Voroshilov，在这次事故后，决定将A-19原T型炮口制退器换成和德国人一样的两室设计。

The weld D / W ratio obtained by simulation is in good agreement with experimental results.

焊缝深宽比的模拟结果与实验结果符合较好。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.
